CSI Lab Continued

Context of Lesson:
This lesson will be the continuation of the CSI lab that students began last class. Students will be doing part B of the lab, drawing conclusions, finishing their calculations/observations and preparing to write a lab report. There will be a brief discussion about who was the murderer after the lab is completed. Students will have a formal lab write up to do for this CSI lab and I will very briefly review what the requirements are and students will be assigned a due date.

Opportunities to Learn
  • Depth of Knowledge: Level 1, 2, 3
  • Prerequisite Knowledge: Students will be applying their knowledge of differing physical and chemical properties to identify an unknown substance through several investigations comparing the characteristic properties of multiple unknown powders.
  • Plans for Differentiating Instruction: I will be differentiating instruction in this lesson by allowing students to continue working in their groups and using a pre-made data table.
  • Accommodations and modifications: To modify this lesson I will be briefly reviewing the procedure for writing a lab report as well as providing written instructions.
  • Environmental factors: For this lesson there will need to be a clean floor space for walking around while doing the lab, and students will have to abide by normal safety procedures.

Materials:

  • Teacher:


  • - All materials required for last class so lab may be continued


  • - Extra copies of lab packet



  • Students:

  • - Lab packet from previous class with data for part A completed




Objectives:
  • - Students will apply concepts about properties of matter and changes in matter to identify an unknown substance.
  • - Students will compare properties of different substances to identify an unknown substance.
  • - Students will differentiate between physical and chemical properties.----

Instruction:
  • Opening
    • -Students are already in the middle of working on the CSI lab, so I will start off by asking how far individual groups have
gotten with their labs to see how much time they should need before doing/ working on their presentations.

  • Engagement



  • - Students will continue to work on their labs, completing the data chart for part B and finishing up with the last bit of testing.


  • -Discussion of data
    • Who killed Mr Doughboy?
    • How did you find out using properties of the substances you were working with?

  • Closure:



  • -After each group has finished presenting, I will hand out the guidelines/template for a lab report and briefly go over it verbally. They will be given a specific due date, about a week later.


    • Students will already be aware of the test on this unit, but will be reminded before the end of class that the test is the last day this week.
    • students will be given a list of topics that we will create as a class in the last couple minutes of class so they are aware of exactly what will be on the exam: physical and chemical properties of matter, different physical and chemical changes, how these can be applied when identifying a substance.


Assessment:
  • - Students will be assessed formally through their lab reports.
  • - Students will be assessed formatively on participating and completing the experiment
